  • the voice codec 412 linked with the terminal controller 400 is connected to a microphone and a speaker through the amplifier 414, and uses Pulse Code Modulation (PCM) to output the voice data through the terminal controller 400 by encoding the voice signal input from the microphone, as well as decode the voice data input from the terminal controller 400 while outputting the voice signal through the amplifier 414 to the speaker.
  • PCM Pulse Code Modulation
  • the amplifier 414 amplifies the audio signal input from the microphone or output to the speaker by regulating the speaker volume and microphone gain according to the control of the terminal controller 400.
  • FIG. 5 is a flowchart illustrating an operational process of message transaction of a digital broadcasting receiving terminal 108 according to the present invention when the terminal receives messages including broadcasting information.
  • the terminal controller 400 receives a message in step 500.
  • the terminal controller 400 proceeds to step 502 to determine whether the input message at step 500 includes broadcasting information.
  • step 502 may be a process of detecting the TID included in the received message, and determining that the received message includes the broadcasting information if the detected TID is equivalent to the TID of message used for transmitting broadcasting information.
  • the terminal controller 400 proceeds to step 504 to extract the broadcasting information from the message.
  • the terminal controller identifies the broadcasting program information in accordance with the extracted broadcasting information.
  • the terminal controller 400 loads the stored EPG data to search for the broadcasting program corresponding to the broadcasting information and extract the information according to the searched broadcasting program.
  • the process in step 506 may be changed according to the information that the received broadcasting information message contains as described above.
  • the terminal controller 400 must extract much more information on many broadcasting programs from the EPG data when the broadcasting information message constructed as described in Table 1 is received, as opposed to that described in Table 5.
  • the process of extracting the broadcasting program information in accordance with whether the broadcasting information message includes the broadcasting program information will be described in more detail with reference to FIG. 6.
  • the terminal controller 400 which has extracted the broadcasting program information corresponding to the broadcasting information included in the message through the step 506, proceeds to step 508 to determine whether a user chooses to view the broadcasting program according to the broadcasting information message. If the user chooses to view the broadcasting program, the terminal controller 400 proceeds to step 510 to identify the starting time and broadcasting duration of the broadcasting program according to the broadcasting information, and compares the identified time and duration with the current time to determine whether the current time is when the broadcasting program is broadcast. If it is determined at step 510 that the current time is when the broadcasting program is broadcast, the terminal controller 400 proceeds to step 518 to change the current channel to another channel through which the broadcasting program is broadcast.
  • the terminal controller 400 proceeds to step 512 to determine whether the current time is when the broadcasting program is broadcast according to the broadcasting information. If it is determined that is the time is when the broadcasting program is not yet broadcasted, the terminal controller 400 proceeds to step 514 to ask the user whether a reservation for the corresponding broadcasting program will be selected.
  • the reservation setting refers to setting in which the user is allowed to watch a specific broadcasting program at a preset time or to record the broadcasting program at pre-arranged time.
  • step 514 if the user selects the reservation, the terminal controller 400 proceeds to step 516 to execute the reservation setting according to the user's selection. Therefore, if the message including broadcasting information is received from the broadcasting information service provider 100, it is possible to watch the specific broadcasting program or to execute the reservation setting through the present invention.
  • FIG. 6 is a flowchart illustrating an operation of the digital broadcasting receiving terminal according to the present invention
  • step 600 determines whether the received broadcasting information message contains additional broadcasting program information. If it is determined that the message includes the broadcasting program information according to the broadcasting information, the terminal controller 400 extracts the broadcasting program information from the broadcasting information message and proceeds to step 508 to determine whether the user chooses to watch the broadcasting program in accordance with the extracted broadcasting information. Thus, in this case, it is unnecessary for the terminal controller 400 to separately extract the broadcasting program information corresponding to the broadcasting information from the EPG data.
  • the broadcasting program information refers to the additional information on the specific broadcasting program as described above, such as the channel where the specific broadcasting program is broadcast, the service provider of the specific broadcasting program, the title of the specific broadcasting program and the starting time and broadcasting duration of the specific broadcasting program.
  • step 600 if the message doesn't include the broadcasting program information according to the broadcasting information, the terminal controller 400 proceeds to step 602 to load the previously stored EPG data.
  • the terminal controller 400 proceeds to step 604 to extract the information on the broadcasting program corresponding to the broadcasting information from the loaded EPG data. Therefore, in the present invention, although the information on the specific broadcasting program is not included in the message, the information on the broadcasting program can be extracted by using the broadcasting information.
  • the present invention allows a user to more conveniently obtain the digital broadcasting program information, activate the digital broadcasting, and reduce the time wasted when a user searches for his/her favorite broadcasting program directly through the menu.
  • a broadcasting operator or a communication operator who functions as a broadcasting information service provider in the present invention, can use the present invention in order to induce users to join the specific broadcasting service.
  • the broadcasting information service provider generates and transmits the message containing the information on the specific broadcasting program to the user, so as to induce the user to join a specific broadcast service.
  • the user is capable of viewing the broadcasting program according to the information included in the corresponding message or executing a reservation setting. Therefore, if the user is obliged to join the specific broadcasting service so as to view the broadcasting program, the broadcasting information service provider can also induce the user to join the specific broadcasting service by providing the broadcasting service information to the user.
  • the present invention is effective for inducing users to join the specific broadcasting service.
  • WAP Wireless Application Protocol
  • PUSH Wireless Application Protocol
  • the present invention has been described with respect to only SMS or MMS-type broadcasting information messages, Wireless Application Protocol (WAP) PUSH formatted messages can also be utilized since the WAP PUSH method also distinguishing types of services using the teleservice ID in a manner similar to that of the messaging method. That is, on the assumption that the teleservice ID: 12345 is a message used for WAP Alert as a specific application used in WAP and the contents of User Data include Text Data, delimiter and CallBack URL, the message shown in the following Table 6 may be generated. Table 6 receiver information 012-345-678-0000 teleservice ID 65491 User data A new mail has arrived. http://www.wapmail.com
  • WAP Alert Message can be transmitted in a manner similar to SMS message.
  • a message in WAP PUSH method which includes broadcasting information instead of the User Data, can also be transmitted according to the present invention.
